Attribute Reference
This reference describes the Visual Net Server functions implemented as an XML-vocabulary. The vocabulary is attribute-based meaning that most directives are used as attributes to the XML-elements that define content entities.
The naming convention for the Visual Net Server functions is: attributes are in small letters, elements and system parameters are in capital letters.
The XML-representation of the functions is described using an informal syntax, usage examples, and with XML-schema definitions where suitable. The syntax convention for the informal syntax is,
<SYNTAX>
<elementName entityTypeName="'yes'" entityAttribute="symbol | constant "/>
